natural compounds which offer various alternatives to the treatment of pain, inflammation and cancer. Their stereoselective synthesis remains therefore a key-challenge towards its use in the pharmaceutical industry. In the present work myrtucommulone A and B were synthesised through metal catalysis with 81 and 72% ee respectively. Thanks to the use of cinchonidine as an organocatalyst, 82 and 84% de were
肉豆蔻内酯属于一类具有药理活性的天然化合物,可为疼痛,炎症和癌症的治疗提供多种选择。因此,它们的立体选择性合成仍然是对其在制药行业中使用的主要挑战。在目前的工作中,肉豆蔻酮A和B是通过金属催化分别以81%和72%的ee合成的。由于使用辛可尼定作为有机催化剂,肉豆蔻酮A和肉豆蔻酮F的de分别达到82%和84%。同时,出现了一种新的合成方法,并为在温和条件下或通过一锅法反应制备肉豆蔻酮衍生物提供了新的可能性。
